Definitions

  • the invention relates to a tool for machining the spline of a crown wheel for mating with a cylindrical spur gear toothed pinion.
  • hobbing For the production of front-toothed wheels is the hobbing known.
  • a milling cutter as a hob used, which divided from one by flutes in cutting teeth Snail exists.
  • the axis of rotation of the hob is arranged at an angle to the axis of rotation of the gear workpiece.
  • Of the Cutting feed of the milling cutter is parallel to the axis of rotation of the Gear workpiece.
  • the invention is based on the object, a cost-effective Machining the flat teeth of a crown wheel for mating with a cylindrical spur gear To allow pinion.
  • the invention makes it possible to have a planer toothing for the pairing with a cylindrical pinion in a cost-effective To produce hobbing process.
  • a milling tool used which has cutting on its lateral surface, each one segment of the spur gear toothing of the pinion correspond, which in the planer teeth of the crown wheel should run.
  • the in a predetermined division in the circumferential direction Corresponding cutting of the milling tool correspond in each case segments of the toothing of the pinion, the fraction corresponding to the number of cutting edges in the tooth pitch are twisted against each other.
  • the milling tool rotates about an axis which is the axis of rotation of the crown wheel workpiece at an angle.
  • the cutting feed of the milling tool runs at an angle to both the axis of rotation of the milling tool as well as the axis of rotation of the crown wheel workpiece.
  • the cutting feed of the milling tool runs at an angle to both the axis of rotation of the milling tool as well as the axis of rotation of the crown wheel workpiece.
  • the planer toothing using the inventive Milling tool on a conventional gear cutting machine milling.
  • the milling tool is made a disc-shaped base body, in whose lateral surface the Cutting in the predetermined angle division are used. This makes it easy to change the cutting possible.
  • the diameter of the milling tool can be essential made larger than the diameter of the pinion. Thereby can have a greater cutting force and a more favorable cutting angle will be realized.
  • the cutting teeth corresponding to the teeth of the pinion be produced cheaply.
  • the cutting edges of the milling tool are in line with a segment of the Ritzels match, which at least a complete tooth profile must complete so that the profile to be generated completely can be milled out.
  • the segment includes some few tooth profiles, with the number of tooth profiles after Diameter and number of teeth of the pinion can be selected. In Most applications are associated with segments three complete tooth profiles favorable cutting properties of the milling tool.
  • Fig. 1 is schematically the basic principle of the invention Process illustrated.
  • Gear machine is a crown gear 10 in one Workpiece holder clamped and around its designated as C-axis Driven rotation axis rotating.
  • a milling tool 12 is stretched in a tool carrier and is around its as a B-axis designated rotational axis driven in rotation.
  • the Milling tool 12 carries at its periphery in its lateral surface used cutting edges 14.
  • the B-axis of the milling tool 12th runs at an angle to the C-axis of the crown wheel workpiece 10.
  • the B-axis of the milling tool 12 is on such axial Distance from the crown wheel 10 set that his Dipping cutting edges 14 into the plane surface of the crown wheel workpiece 10, to generate the spline 16.
  • the milling feed for the generation of the planer teeth 16 takes place thereby, that the crown wheel workpiece 10 and the milling tool 12 in the in the drawing with X-axis direction against each other to be moved.
  • the X-axis is at an angle to the C-axis, around which the crown wheel workpiece 10 is rotated as also at an angle to the B axis, around which the milling tool 12th is turned.
  • the feed direction of the X-axis can be the Cut C-axis so that generates a straight-plan teeth or can cross the c-axis off-center, so that a Oblique-planer is generated.
  • the milling tool 12 is shown in Figures 2 and 3 in detail shown.
  • the milling tool 12 has a circular disk-shaped basic body 18, which rotatably by means of a splined connection 20 is placed on a drive shaft.
  • radial slots 22 are incorporated in the outer jacket surface of the main body 18 .
  • the slots 22 are in the same angular pitch on the Scope of the body 18 distributed.
  • In each slot 22 is one each Cutting edge 14 used.
  • the two plane surfaces of the main body 18 are each covered by cover plates 24 and 26.
  • the cover plates 24 and 26 are made with the main body 18 by axially parallel screws 28 braced, each at an angle offset between the slots 22 are arranged.
  • the cover plates 24 and 26 close the slots 22 at the axial Planar surfaces of the body 18 and support the cutting 14 laterally.
  • the cutting edges 14 consist of a cutting plate 30, the one has rectangular basic shape. With this rectangular basic contour the cutting plate 30 is inserted into the slot 22.
  • the cutting plate 30 is a preferably circular Breakthrough 32 recessed.
  • each threaded hole from the outer circumference of the body 18 at an angle in the slots 22.
  • this threaded hole is designed as a grub screw clamping screw 34 screwed.
  • the clamping screw 34 engages with her Tip in the opening 32 and thereby presses the insert 30 against the bottom of the slot 22.
  • the insert 30 is in this way by the clamping screw 34 at the bottom the slot 22 set while the means of screws 28 braced cover plates 24 and 26, the cutting plate 30 at tension and fix their radial edges. After a loosening the cover plates 24 and a unscrewing the clamping screw 34, the cutting plate 30 can be replaced.
  • the cutting plates 30 each protrude with a cutting profile 36 over the lateral surface of the Base 18 and the cover plates 24 and 26 addition.
  • the cutting profile 36 has a profile shape which exactly one segment of the tooth profile of the spur pinion 40 corresponds, which with the planer 16 of the Crown wheel 10 is paired.
  • the cutting profile 36 with a segment of Gearing of the pinion 40 match, which three complete Teeth includes.
  • the cutting profile 36 may also be with a segment of the pinion 40, which is a different number of teeth However, the cutting profile at least one complete tooth profile must be complete, so that a complete Tooth profile can be milled out and produced.
  • the cutting profile 36 of the blades 14 has a direction of rotation the cutting tool 12 facing cutting edge 38, the is preferably formed with a clearance angle ⁇ .
  • the cutting profiles 36 in the various slots 22nd used cutting edges 14 differ in the way that the cutting profile 36 of each cutting edge 14 each one segment the teeth of the pinion corresponds to that of the Segment of the circumferentially of the milling tool 12 adjacent Cutting edge offset by an angle, one of the Number of cutting edges 14 corresponding fraction of the tooth pitch of the pinion corresponds.
  • Fig. 3 is, for example, to recognize that the Cutting profile 36 of the upper edge 14 relative to the diametrically arranged lower cutting edge 14 by half a tooth pitch is offset.
  • the milling tool 12th not only can wear a set of cutting 14, the one Tooth pitch of the pinion correspond, but that in the circumferential direction consecutively two or more sets of Cutting 14 can be arranged, with each set each Cutting profiles 36, resulting in a tooth pitch of the pinion.
  • the speed of the milling tool must be 12 according to the number of sets of cutting 14 are modified so that the Konradswerk GmbH 10 to a tooth pitch rotates while the milling tool 12 to rotates an angle corresponding to a set of blades 14.
